WlRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 752,948, dated February23, 1904. Application filed December 19, 1903 Serial No. 185,858. (Nomodel.)

To all whom it may concern: 7

Be it known that we, SIDNEY Bnonwon'rn and HERMAN F. WULLSTEIN, citizensof the United States, residing at Littlerock, inthe county of Lyon andState of Iowa, have invented certain new and useful Improvements inWire-Stretchers; and we do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters of reference marked thereon.

The present invention has for its object to provide a simple andpractical device for stretching wires for fences, telegraph, telephone,electric-light lines, or for any other purpose in which awire-stretching device may be found useful; and it consists of awirestretcher constructed substantially as shown in the drawings andhereinafter described and claimed.

Figure l of the drawings is a side elevation of the completewire-stretcher constructed in accordance with our invention; Fig. 2, adetail view in perspective and on an enlarged scale of one of thewire-clamps and its connections; Fig. 8, a similar view of thewire-clamp connected to the opposite side of the hand-lever to that ofthe former clamp; Fig. 4, a perspective view of the end of the cam-jaw;Fig. 5, a detail sectional view showing a portion of each cam-jaw andthe bar to which said jaws are connected.

In the accompanying drawings, A represents a hand-lever formed with aplurality of perforations or holes I) and notches a, said holesreceiving a clamping-screw cto hold to said lever the double arms B ofone of the wire-clamps, thereby rendering said clamp adjustable upon thelever as circumstances require, and the notches are to receive a yoke Cupon the opposite clamp and admit of the clamp being adjusted upon thelever. The extremities of the arms B terminate in eyes cl, through whichthe clamping-screw 0 extends, while the yoke C is closed and slips overthe end of the lever A and engages one of the notches therein, the armsand yoke being shown more clearly in Figs. 2 and 3 of the drawings. Thearms B and the yoke C are each a part of the slotted bars D E,respectively, the construction of the bars being the same, the formerhaving elongated slots and the latter elongated slots 6. The bar D isconnected to a shank F by means of pins f, by which said bar isadjustable thereon, and the bar E is connected to the shank G by pins g,the pins in both instances extending through the slots in the bars andare fastened thereto and headed.

Pivoted to the bar D are toggle-links H I, and to the bar E are pivotedsimilar togglelinks J K, andto eachpair of-toggle-links are pivotedcam-jaws L M and cam-jaws N 0, respectively, as shown in Figs. 2 and 3of the drawings. The shank F has a curved support It, to which arepivoted the cam-jaws L M,

and the shank Gr has a similar support 2', to which are pivoted thecam-jaws N 6, the curved supports being above the plane of the shanks,so that the slotted bars and the togglelinks will be below the plane ofthe cam-jaws. v

The cam-jaws L N are plain and of the same thickness, while the cam-jawsM 0 have raised guide-flanges Z m, respectively, to form guides for theformer jaws and guides for the wire passing between the jaws when thewire is being stretched.

It is evident that in the-description of the invention many changes andmodifications may be made in the several details of construction withoutdeparting from the essential features of the invention, and we thereforedo not wish to limit ourselves to the precise details of construction,but leave the invention open to such changes as would come withinordinary mechanical judgment.

Having now fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. A wire-stretcher comprising asuitable hand-lever, two clampingdevices, each adjustably and removably connectedto the lever andconsisting of a shank and curved support, a bar having elongated slotsadjustably connected to the shank, pivoted cam-jaws upon the support,one of which has a raised guideflange, and toggle-links pivotallyconnected connecting the slotted bar With'the jaws, one of the jawshaving araised guide-flange, substantially as and for the purposespecified.

In testimony whereof We aflix our signatures I 5 in presence of twowitnesses.
